Abstract (en)
[origin: WO8202610A1] On a first keyboard (4) the time value of each musical note and/or the time value of each pause of the musical sequence to be reproduced is introduced. After the introduction of each note value, the respective pitch value of this note can be introduced with the aid of a second keyboard (50). The introduced sequence can include up to 8 measures and is reproduced repeatedly after actuating a start switch (11) on a visual display (13) and/or with an acoustic output (34) in a frequency which is selected with the help of a switch (20). The visual display (13) has (4) seven segments elements which show the sequence continuously, measure after measure. The acoustic output (34) can produce, at choice, white noise signals or sounds. The white noise signals have impulses which decrease exponentially from a maximum.
